The problems seems to be associated with either sync SCSI or disconnect/
reconnect. I did a two line modification to sgiwd93.c which disables
sync and disconnect/reconnect. I now have since about a hour running:
dd if=/dev/sda of=/dev/zero &
dd if=/dev/sdb of=/dev/zero &
dd if=/dev/sdc of=/dev/zero &
find / /ext -xdev | cpio -o -H crc -F /dev/nst0 --verbose
No problem so far. (Except that SCSI performance even with only single
disk activity is further converging to zero ...)
